High- $Q$ optical cavities in hyperuniform disordered materials

Timothy Amoah and Marian Florescu

Phys. Rev. B 91, 020201(R) (2015) - Published 20 January, 2015

Hyperuniform disordered materials are a class of photonic solids with a constrained randomness that have short-range order and long-range statistical isotropy. In these materials, calculations suggest a new type of high-Q localization mechanism in optical cavities, that has no analogue in periodic or quasi-periodic photonic crystals.

Hydrostatic pressure-induced modifications of structural transitions lead to large enhancements of magnetocaloric effects in MnNiSi-based systems

Tapas Samanta, Daniel L. Lepkowski, Ahmad Us Saleheen, Alok Shankar, Joseph Prestigiacomo, Igor Dubenko, Abdiel Quetz, Iain W. H. Oswald, Gregory T. McCandless, Julia Y. Chan, Philip W. Adams, David P. Young, Naushad Ali, and Shane Stadler

Phys. Rev. B 91, 020401(R) (2015) - Published 5 January, 2015

By means of alloying appropriate amounts of MnNiSi and MnFeGe, materials are found that undergo a paramagnetic to ferromagnetic transition close to room temperature, accompanied by a huge volume change. Thanks to this volume change, application of moderate pressures leads to a remarkable enhancement of the magnetocaloric response. Work like this may open new opportunities in the development of new solid-state magnetic refrigeration devices.

Two distinct kinetic regimes for the relaxation of light-induced superconductivity in $L a_{1.675} E u_{0.2} S r_{0.125} Cu O_{4}$

C. R. Hunt, D. Nicoletti, S. Kaiser, T. Takayama, H. Takagi, and A. Cavalleri

Phys. Rev. B 91, 020505(R) (2015) - Published 29 January, 2015

Using femtosecond laser excitation to melt stripe order in La $_{1.675}$ Eu $_{0.2}$ Sr $_{0.125}$ CuO $_{4}$ , the authors reintroduce $c$ -axis coherent coupling and observe the formation and subsequent relaxation of a competing state, which can be induced up to 80 K. In addition, they also find two distinct kinetic regimes above and below the spin-order transition at $T_{S O}$ ~25 K.

Unconventional superconductivity in quasi-one-dimensional ${Rb}_{2} {Cr}_{3} {As}_{3}$

Zhang-Tu Tang, Jin-Ke Bao, Yi Liu, Yun-Lei Sun, Abduweli Ablimit, Hui-Fei Zhai, Hao Jiang, Chun-Mu Feng, Zhu-An Xu, and Guang-Han Cao

Phys. Rev. B 91, 020506(R) (2015) - Published 30 January, 2015

Following the authors’ own discovery of superconductivity in quasi-one-dimensional K $_{2}$ Cr $_{3}$ As $_{3}$ , the analogous compound Rb $_{2}$ Cr $_{3}$ As $_{3}$ is synthesized for the first time in polycrystalline form. Bulk superconductivity emerges at 4.8 K. Further work is needed to verify the nature of the superconducting state.

Anisotropic $H_{c 2}$ , thermodynamic and transport measurements, and pressure dependence of $T_{c}$ in $K_{2} {Cr}_{3} {As}_{3}$ single crystals

Tai Kong, Sergey L. Bud'ko, and Paul C. Canfield

Phys. Rev. B 91, 020507(R) (2015) - Published 30 January, 2015

K $_{2}$ Cr $_{3}$ As $_{3}$ is a newly discovered compound that has a superconducting transition temperature of 6.1 K. Special interest in it stems from the fact that it crystallizes in a hexagonal lattice containing a quasi-one-dimensional chain structure made of (Cr $_{3}$ As $_{3}$ ) $^{2 -}$ . With careful measurements on single crystals this research team from Iowa State University demonstrates that although the material can be considered to be close to quasi-one-dimensional in a crystallographic sense, the data support a three-dimensional nature with Fermi-liquid-like properties.

EDITORS' SUGGESTION

Competing superconducting and magnetic order parameters and field-induced magnetism in electron-doped $Ba {({Fe}_{1 - x} {Co}_{x})}_{2} {As}_{2}$

J. Larsen, B. Mencia Uranga, G. Stieper, S. L. Holm, C. Bernhard, T. Wolf, K. Lefmann, B. M. Andersen, and C. Niedermayer

Phys. Rev. B 91, 024504 (2015) - Published 13 January, 2015

This paper presents a systematic study of the magnetic and superconducting properties of Ba(Fe $_{0.95}$ Co $_{0.05}$ ) $_{2}$ As $_{2}$ as a function of temperature and external magnetic field using neutron scattering and muon spin rotation. Calculations based on the five-band Hubbard Hamiltonian reproduce the physical properties of the coexistence region of Ba(Fe $_{1 - x}$ Co $_{x}$ ) $_{2}$ As $_{2}$ . Below the superconducting transition temperature the magnetic and superconducting order parameters coexist and compete. An external magnetic field significantly enhances the magnetic order parameter within the superconducting state. This behavior can be caused by the vortices, which in the superconducting state can slow down and locally freeze spin fluctuations.
